This library provides a set of tools that can be useful in many machine learning applications (classification, clustering, regression, etc.), and particularly helpful if you use scikit-learn (although this can work if you have a different algorithm).
Most machine learning problems involve an step of feature definition and preprocessing. Feature Forge helps you with:
- Defining and documenting features
- Testing your features against specified cases and against randomly generated cases (stress-testing). This helps you making your application more robust against invalid/misformatted input data. This also helps you checking that low-relevance results when doing feature analysis is actually because the feature is bad, and not because there's a slight bug in your feature code.
- Evaluating your features on a data set, producing a feature evaluation matrix. The evaluator has a robust mode that allows you some tolerance both for invalid data and buggy features.
- Experimentation: running, registering, classifying and reproducing experiments for determining best settings for your problems.
pip install featureforge.
